After this activity, you should be able to do the following:
ggmap() function along with ggplot2 functionsgeom_map()ggplot2 features to a map created from geom_map()leaflet, including adding points and choropleths to a base map
Take a look at these to get motivated/inspired to make your own geospatial visualizations:
As the number of electric vehicles used increases, so do the number of electric vehicle charging stations and ports. The Open Charge Point Interface (OCPI) protocol is a standard for classifying stations according to (1) location, (2) number of charging ports, and (3) number of connectors/plugs (multiple connectors can be on a port, but only one can be used at any given time). Charging equipment is separated into Level 1 charging, Level 2 charging, and DC fast charging, in increasing speed of charging. Read more about these standards here.
According to the Alternative Fuels Data Center (AFDC), as of January 2024, there are 61,124 public electric vehicle charging stations in the United States, and they have 163,191 ports. These numbers have approximately doubled in the last three years:

Where are these stations? How is there distribution across the country related to land area? population? electric vehicle ownership? demographic measures such as socioeconomic, race, and ethnicity?
